LED's will grow weed! not going to be super dense heavy nug but! they will get the job done. If you cant go cutting a bunch of holes in ur ceiling and running intake and exhaust lines through your room then LED's are they way to go! Plus you wont have to change a bulb for like what 50,000 hours? LED's seem to pay for them selves over time cause you dont have to keep replacing bulbs. And they look so damn cool!:rastasmoke:
